Synopsis:

Abstract:

This course aims to give an overview to concepts and methods in the broad field of open quantum systems and their experimental applications. The course is taught in physics style by choosing the most explicit rather than the most general mathematical setup to illustrate phenomena.

This is a merger of courses TCM334 (weeks 1–6) and TCM335 (weeks 7–13) provided by the University of Helsinki, in collaboration with Aalto University, to CTU students in the framework of the DigiQ Digitally Enhanced Quantum Technology Master. To complete the course, students are expected to attend the on-line lectures and exercises (in real time or the recorded version) by the lecturers Paolo Muratore-Ginanneschi, Jukka Pekola and Bayan Karimi.
